I am new to vray and struggling to understand why my render time has gone up 7 times since I baked the GI, is this normal???
The shot is 1,500 frames. it involves a very slow move into a group of objects in a room. only camera moves.
I started the scene simply using the GI presets - I chose "01F: special camera IRR+LC" during scene setup the shot was taking approx 8 mins per frame at 1080p. I rendered 60 frames, but there was a slight flicker in the shadow areas.
I baked the GI, then started to render a few frames, but the render time has now lengthened to 58 mins per frame. I have only rendered a couple of frames so far, I can't see any flicker, but would need more frames to make a judgement ...
Am I doing something wrong?? why is the render time so massive? I feel like I could render more quickly using 2 passes of brute force (although can't test it yet as computer is processing the other). Should I try this?
I understand that I need to be patient when rendering GI, but this seems to go against the argument that Vray is a much quicker physical renderer than ... the others.
